We do have some javascript hooks, but none that will accomplish what are you trying to do. The backend hooks provide support for what you've done on the front end to the the backend. </p> https://legacy.forums.gravityhelp.com/topic/calculate-shipping-based-on-quantity#post-33911 Tue, 30 Aug 2011 11:22:56 +0000 katart 33911@https://legacy.forums.gravityhelp.com/ <p>Thanks for the response David. Using hooks is very new to me, but I am always up for a challenge. Does this mean I can eliminate my jQuery calculations and let the hooks to the work, or is it a bit of both?</p> <p>I'm not sure where to start, but I guess I should start reading about WP hooks. </p> https://legacy.forums.gravityhelp.com/topic/calculate-shipping-based-on-quantity#post-33756 Mon, 29 Aug 2011 07:01:40 +0000 David Smith 33756@https://legacy.forums.gravityhelp.com/ <p>Hi Katart,</p> <p>Most likely the issue is that although you are changing the shipping price on the front end, Gravity Forms does not know that the shipping price has been updated. You need to update this dynamically in the backend as well using the <a href="http://www.gravityhelp.com/documentation/page/Gform_product_info" rel="nofollow">gform_product_info</a> hook. You will see that all of the $product_info is passed to this hook and can be modified as needed. This includes the shipping price. </p> https://legacy.forums.gravityhelp.com/topic/calculate-shipping-based-on-quantity#post-33715 Sat, 27 Aug 2011 17:07:59 +0000 katart 33715@https://legacy.forums.gravityhelp.com/ <p>Here is the page: <a href="http://www.bankstreettheater.com/beta/prices/gift-cards/" rel="nofollow">http://www.bankstreettheater.com/beta/prices/gift-cards/</a> </p> https://legacy.forums.gravityhelp.com/topic/calculate-shipping-based-on-quantity#post-33689 Sat, 27 Aug 2011 13:27:50 +0000 Chris Hajer 33689@https://legacy.forums.gravityhelp.com/ <p>Can you post a link to your page with the form in it? </p> https://legacy.forums.gravityhelp.com/topic/calculate-shipping-based-on-quantity#post-33639 Fri, 26 Aug 2011 09:56:38 +0000 katart 33639@https://legacy.forums.gravityhelp.com/ <p>Well, I have successfully added a USD symbol to the value of the hidden shipping input field, but I still am receiving a validation error for a Valid Value.

Here it is if anyone wants to use it or optimize it:</p> <pre><code>$(&#39;.ginput_quantity&#39;).keyup(function() { var sum = 0; $(&#39;.ginput_quantity&#39;).each(function() { sum += Number($(this).val() * .50); }); $(&#39;.gfield_shipping .gform_hidden&#39;).attr(&#39;value&#39;,parseFloat(sum).toFixed(2)); });</code></pre> <p>I have a list of Products with the Quantity field attached (by default) and want to add a $.50 cent per Quantity shipping cost to the total order. This jQuery snippet adds the total Quantity value and multiplies it by .5 and then places that value in the hidden input of the Shipping field.</p> <p>Since I am a newbie at jQuery, I'm sure there is a better to do this and would love to hear about it.</p> <p>Thanks </p>
